barefoot.

so if it is Kabuto whats going to happen?

he is going to save sasuke with his sage mode, say he realized he was a dick and thanks itachi for making him realize his faults, and will save sasuke as a thanks to itachi, but it by no way changes the fact that they are enemies, naruto gets saved by tsunade suiciding for him the way gaara got saved, friendship mode to the max enabled.
Naruto I luvs you
Sasuuuuukeeeeeeeeeeyyyyyyyyyyyyy
*makes out*

that pretty much does sums it up.
